Selektive Oxidationsreaktionen mit molekularem Sauerstoff in komprimiertem Kohlendioxid
… oxidation of alcoholic intermediates. Since C-C-scission reactions are detected only to a very small extend, tertiary carbon atoms are transformed to the corresponding alcohols with high selectivity. The obtained product distributions suggest that the strong influence of acetaldehyde is related …

Structure and activity relationships of bimetallic catalysts for aqueous phase reforming and the water-gas shift reaction
… dehydration/hydrogenation routes to [C-O] bond scission. Electron energy loss spectroscopy (EELS) maps confirm that while for individual particles Re remains well mixed with Pt in PtRe/MWCNT, the Re metal is well dispersed on the high surface area activated carbon support of PtRe/C, allowing …

Kinetics of Methyl Ketone and Levulinic Acid Oxidative Scission Over Supported Vanadium Oxide Catalysts
… in high yields through methyl a-carbon oxidative scission over supported vanadium oxide catalysts. However, the high selectivity of methyl scission during LA oxidation appears to be unexpected according to the trends observed during the analogous oxidative scission of methyl ketones (e.g., …

Spectroscopic characterization of iron-oxygen intermediates in human aromatase (CYP19A1)
… one of which involves a carbon-carbon bond scission and aromatization. The catalytic mechanism of P450s has been long studied and it is well known that an oxo-ferryl π-cation radical, known as “Compound 1” in P450 chemistry is the reactive intermediate that catalyzes most of the reactions of …
